CALVIN YOUNG, OF AUBURN, NEW YORK.

:BULLET-MACHINE.

Specication of Letters Patent No. 21,463, dated September 7, 1858.

To all whom it may concern:

Be it known that I, CALVIN YOUNG, of the city of Auburn, county ofCayuga, and State of New York, have invented a new and useful Machinefor Making Bullets from Cold Lead by Pressure; and I do hereby declarethat the Jfollowing is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, numbered from No.l to No. 10, inclusive.

The general construction of this machine is as follows: lst,V as shownby draw'ings Nos. l, 5., and 7 P represents the main bed or foundationupon which stands the main trunk B, into which, at the top, the dies A,A are set as shown in Figure No. l. Attached to vthe inain trunk B arefour uprights Z Z, connected together by ltwo cross bars T, T, throughwhich the ,punch -bar M moves, and by which it is guided. Motion iscommunicated to the punch bar M by means of a traveling beam H throughwhich M passes, and is adjusted to its proper `height by .means of Vascrew thread cut upon it, and is held in its place yby a set nut S asshown in Figs. Nos. 1 and 7. Power is communicated to I-I .by twoconnecting rods H H as shown in Figs. Nos. 5 and .7, which take hold ofit at each end outside of the uprights Z Z between which it moves, andby which it is kept in its place and 'guided aright. `Connecting rods HI-I pass through the bed plate P and take hold 4of cranks R R upon eachend of shaft F which is driven by Igear wheel H, which is driven bypinion H upon shaft S, to which power is applied by means of cranks orotherwise.

The main body or 'trunk B is made in two parts B and C as shown on Figs.1 and `8. B is the fixed part, being bolted 4to the main bed orfoundation P. C is a working piece, being fitted between Atwo flanges.`and connected to `them by pin C, `upon which it rfreely turns and isclosed into its proper place by the cam D, `see Figs. l, '2, and whichcani is driven by pinion F upon shaft S. The movable piece C is thrown.back or open by the spring K. See Fig. No. l.

rIhe dies, a, a, for forming the bullet, are 'fitted and rmly fixed; theone half into the permanentpart B and `the other half into the movablepart C, by which Vthey are closed and opened. The dies a a have each alat-eral punch A" fitted into and through them, the outer end of thepunches A fitted permanenti;7 into cross bars, which are .fit-ted freelyinto a groove cut in the back of each of the dies. The groove is ofsufficient dept-h to allow `the cross bars to move freely a shortdistance toward the face of the dies, which carries the inner end of thepunches A A beyond the inner surface of the dies. See Figs. Nos. l, 2,and 3. The cross bars .project at each end beyond rthe side of the diessufficient to receive cross connecting bolts A A, which .are of theproper length to allow the dies `to open sufficiently 4for the builletto drop between them Vat their 4lower extremities. See Fig. 3. Theconnecting bolts are fitted loosely through the cross bars, so that theymay slide `freely and allow the dies to close and open to their properdistance. Upon those cross connecting :bolts .between the cross fbarsthere are :fitted collars or rubber A, see Figs. '2 and 3, which actupon the insideofithe cross bars at the point where the cross connectingbolts `pass through them, which force the cross bars back to theirproper place when the dies are closed, and thus convey the lateralpunches c a bac'k to `their places, yso that the inner ends are 4evenwith lthe inner surface of fthe dies, Aand thus help form .a smallportion of -the bul'lets surface.

The punches and Jtheir appurtenances last above described are for thepurpose of removing the bullet from the dies after it is formed.

At the top and upon the back of :the main 'trunk B the parallel Ways J,as shown by Figs. Nos. l, 2, and il, are attached, between which theslide I is iitted and moved freely Vlengthwise by the cross arm I-I, ateach end of which the connecting rods G -G take hold `as shown by Fig.No. 2, which at the other end take hold of one driven Aby crank F. Uponthe end of the axle of the cam D lwhich have their bearings in the eyebolts E, E that pass through the main trunk B and are nutted at the'back side as shown by Figs. Nos. 2 and 5, the cranks F F are slotted attheir outer ends to facilitate 'the adjusting `of the length of the runof slide I. The connecting rods G G are slotted at one end so that Atheslide I remains at rest for a short space of time at each end of itsrun. Over the top of slide I cap K `is ittedfand `bolted to the ways Jthrough which there is an orifice suitable to admit the lead vwire S,

which passing through K enters a corresponding orifice in I, as shown inFigs. l and 2, and passes through I until it rests upon a gage screw R,by which the length of lead, level with plate K, is regulated. The slideI in moving forward passes its orifice under the elastic roll Y, whichis drawn by the bearings at Y so as to press snugly upon slide I as itmoves along under it, as shown by Fig. No. 4. Slide I has a groove cutin its lower side lengthwise, cor responding to its orifice and the gagescrew R so as to admit of the screw vbeing raised to its proper placewithout interfering with the movement of the slide I.

The last above described part is for the purpose of gaging,`cutting, anddepositing the lead into the dies.

Directly over the above mentioned part there are two rolls N N as shownin Figs. Nos. 1, 5, and 6, which have their bearings in frame O. Theouter roll has its bearings in the movable boxes O which are forcedinward by set screws P, by which means the rolls are forced together.The vrolls are formed, in part, of rubber, by which means the surface ofthe rolls are rendered sufficiently elastic to prevent their marring thelead wire, as it passes between them. The lead is guided to and betweenthe rolls by passing through a guide fastened at arch R which isfastened upon frames O.

Motion is given to the rolls by arm C as shown by Figs. 5 and 6, whichis fitted upon the outer end of the shaft ofthe inside roll, and isfitted so as to turn freely around the shaft. Inside of the arm C is atoothed wheel W which is fixed fast upon the shaft. This wheel is actedupon by means of hand M which is connectedv to the arm C and is held incontact with the teeth of the wheel by means of a spring, so that themotion of the arm downward turns the wheel W and rolls N, N. The arm Cis raised back to its place by means of spiral spring I as shown by Fig.No. 5 which is attached, the one end to the arm, and the other to theouter end 0f the arch piece R at T see Fig. 6.

While the arm is moving upward or back to its place, the spring hand Mis drawn backward over the teeth on wheel W which allows the rolls toremain atrrest during that part of the movement of the arm. The arm isdrawn forward or down by the connecting rod D which connects arm C tolever D which is acted upon by cam E which is fixed upon one of theouter arms of cam D, and inside `of crank F, as shown by Figs. 2 and 5.The direction of the cam is indicated by the arrow (Fig. 5) and actsupon incline and arc E which is fast to lever I, and forces it downwardin slotted guide E as shown in Figs. 5, and 9, lat the top of whichthere is a Vregulating screw by which the amount o `n1otion of lever Dis regulated,

which also governs the distance of motion of arm C and rolls N N. Thelever D is raised back to its place by the spiral spring I.

The last above described portion of the machine is denominated the feedworks, and takes the lead S from a reel or coil whereV it may have beenplaced for that purpose.

The foregoing specification of the construction of the principal partsof the machine is given and the materials used for the same may be ofcast iron, or wrought-iron, or any other suitable metal or composition.

The following is a description of the man ner of operating the machine:Motion being given to shaft S which carries gear pinions H and F, whichgive motion to wheels H and F, the direction of which is indicated byarrows. Wheel H upon shaft F turns the crank It', which work connectingrods X and raise traveling beam X, which carries the punch M to itsproper height to admit of slides I passing under it. While A.

the punch is in the dies, the cranks R R are upon their lower center.The cam D has its flattened part a little past the lower center, and itsfullest part holds the dies firmly together. The cranks F, F are upontheir back center, parallel with connecting rods G Gr which carry slideI back to its proper place, so that the orifice in it near the front endis directlyT under the orifice in cap K in which the lead wire Sremains,

having been passed through its guide at the top of R and passed betweenthe rolls N N and its end inserted in said orifice. At this point thecam'E rests upon the incline E, pinion F turnsl wheel F, which carriesthe crank F upward and the cam E over the incline, which forces thelever D downward and turns the arm C a corresponding distance, carryingthe wheel `W and the rolls N N which force the lead S down through theorifice of I upon the gage screw R. During this motion of the feedworks, the slide I which receives and cuts the lead, stands at rest bymeans of slots in the connecting rods Gr, Gr, where they take hold ofthe cross bar H. At this time,

the feed works have completed their motion.

The cam E remains 1n the arc E and holds the feed works still, and thelead in its place while at this time the connecting rods Gr, G haveadvanced sufficient to act upon arms H, by which means the slide I isforced forward and the portion of lead that is in it is sheared off,between the upper surface of I and the lower surface of K which come Ain close contact so as to out the lead smoothly. As the lead is beingcut off cam E is passing out of arc E, so the feed works may resumetheir proper position as hereinbefore described ready for the nextaction. The -slide I continues to move for.

ward, carrying in its orifice the piece of lead cut off and passingunder the elastic roll Y the lead is loosened in the orifice by thepressure of the roll upon it so as' to drop its lower end upon the uppersurface of B, which is parallel and even with the upper surface of thedies and is carried along in the orifice of I until it is broughtdirectly over the opening of the dies into which it drops. Thus the leadis gaged, cut and deposited in the dies all with the same instrument. Atthis point of' the operation the punch, which forms the cavity and buttof the bullet, and it attached to the lower end of punch bar M, is atits upper extremity of the run, the cranks R It being upon their uppercenters and the cranks F F on their forward centers parallel withconnecting rods G G. The slide I remains at rest at this point the samelength of time that it does at the opposite end of its run, so that thepunch passing down enters the end of it, into the orifice in slide Isufficient to remove or force down the lead, if it should not havefallen into the dies previously. At this instant the slide I starts backfrom under the punch, the front part of the orifice being cut away toadmit of this movement, and moves back to its former position to receiveanother portion of lead. In the meantime the punch passes into the diesand presses the bullet into shape, the dies being closed by the cani D.As the punch recedes from the dies the cam D turns its flattened parttoward the movable part of the trunk C into which the one half of thedie is fitted, which allows C to open the dies, being forced back by thespring K and turning upon the pin C.

Thus the dies are opened without restrict-ion until they are checked bythe cross connecting bolts A which pass through the two cross bars inthe back of the dies which carry the lateral punches A A, and whichmotion draws the cross bars forward in the slots, which projects thepunches A A through and out of each half die, so that the bullet must beremoved from either part of the die, to which it may adhere. The bulletwhen thus removed falls down through the lower extremity of the diesinto a conducting tube in which it passes through P into the portion ofthe conductor that is curved so as to pass the bullet around the wheel Hand thence into a receiver arranged for that purpose.

That I claim as my invention and desire to secure by Letters Patent- 1.The application of' elastic rolls for the purpose of feeding lead wireinto the machine, substantially as described in annexed drawings andspecification. A

2. The application of the arrangement or device for gaging, cutting anddepositing the lead into the dies by the same instrument; and the mannerof constructing and operating this portion of the machine, substantiallyas described in annexed drawings and specification.

3. The application of the arrangement or device of lateral punches forremoving the bullet from the dies substantially as described in annexeddrawings and specification.

The above is a full description of improvements in the inode ofconstructing machines for the manufacture of bullets from cold lead bypressure in respect to which a caveat was filed. by said CALVIN YOUNG,in the month of April 1857 in the secret archives of the Patent Oflice.
